RFID stands for radio frequency identification. They are tags that use radio waves to transmit data. They are heavily used in Inventory tracking, and should eventually replace barcodes. Passive radio frequency identification uses no internal power and can pick up the very faint signal from an antenna. An active radio frequency identification has power and transmits much stronger and accurate data. It can power up just enough to transmit data back to antenna. It can also store small amounts of EPROM data. They can be mass produced at a very low cost
